LEATHER FORMING OR MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 564,641, clated July28, 1896.

Application filed October 16,1895.

To aZZ whom it may concern.-

Be it known that we, AUSTIN E. PERRY, of Wakefield, in the county ofMiddlesex, and XVILLIAIWI GORDON, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Leather Forming or Molding Machines, of which thefollowing is a specification.

This invention relates to machines for molding leather by pressurebetween two opposed surfaces, and it has particular'reference tomachines for making outer soles of springheel boots and shoes, suchsoles being oifset to form an incline between the heel and shankportions of the sole in amanner well understood.

The invention has for its object to provide an improved machine adaptedto quickly and effectively form the ofiset or inclined breast on a sole;and it consists in the improvements which we will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a front elevation of our improved machine. Fig. 2represents a top plan View. Fig. 3 represents an end elevation. Fig. 4represents a section on line 4 4 of Fig. 2. Fig. 5 represents a partialelevation and partial section of portions of the machine, showing theoperation of molding the sole. Fig. 6 represents a View similar to Fig.5, the scoring device being omitted. Fig. 7 represents a sectional viewof a portion of a sole as formed by the improved machine. Fig. 8represents a modification.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, ct represents a supportingframe having fixed bearingsfor a shaft b, to which is affixed a bed-roll c. Said bed-rollhas twobeveled peripheral surfaces 2 3, formin g a groove, and a cylindricalperipheral surface at'at one side of said groove.

cl represents a yoke or frame which is mounted to oscillate upon pivotsor centers (1 d and is movable toward and from the shaft 6 and bed-rollc. The yoke 01 is provided with bearings in which is journaled a shafte, to which is'affixed an indenting-roll f, the periphery of Serial No.565,838- (No model.)

which has a milled or corrugated angular edge coinciding with the bottomof the groove in the bed-roll, the said indenting-roll being placeddirectly over the bed-roll, so that the two are adapted to cooperate inbending a sole 3 in the manner shown in Figs. 5 and 6. The swingingmovement of the yoke 61 enables the indenting-roll to be adjusted towardand .indicated by the'arrows in Fig. 3 by any suitable means, such as adriving-shaft h, apinion 71 thereon, a gear j on the shaft b, meshingwith said pinion, and intermeshing gears k, affixed respectively to theshafts b and e. m represents a circular knife or scoringdisk which islocated beside the indenting-- roll and occupies such position that itcuts into or scores the upper surface of the sole along a line over thecylindrical portion 4 of, the bed-roll, said portion supporting theleather under the pressure of the scoringblade. ,7 1

The object of the scoring-blade is to cuta transverse incision s in theupper surface of the sole at one edge of the incline or offset 5 formedby the conjoint action of therolls c and f, as shown in Fig. 5, saidincision enabling the sole to be readily bent to form a reentrant angleat the upper edge of the breast or incline s on the under side of thesole. The scoring-disk m is attached to a holder m, which is mounted torotate upon a stud m secured to a vertically-adj ustable slide or blockm the stud m being horizontally adjustable in said block, so that thescoring-disk can be adjusted horizontally toward and from theindenting-roll to vary the distance between the incisions and the bottomof the groove formed in the sole by the indenting-roll, and alsoadjusted vertically to vary the depth of the incision s or toaccommodate the scoring-disk to soles of different thickness. Thehorizontal adjustment of the scoring-disk is effected by means of ascrew-thread connection between the stud 'm and the slide m a check-nutm being employed to hold said stud at any point to which it may behorizontally adjusted. The Vertical adjustment of the scoring-disk iseffected by means of an adjusting-screw m, having a screw-threadconnection with the yoke d and journaled in the slide m so that when thescrew is raised or lowered by its rotation it will impart a similarmovement to the slide.

In order to provide for adjustment of the scoring-disk independently ofthe indentingroll, we connect said disk and roll by means of a pin 71,affixed to the disk and entering a slot 0 in the indenting-roll, saidpin and slot constituting a self-adjusting connection "which maintainsan operative engagement between the roll and disk, so that the disk ispositively rotated by the roll and permits independent adjustment ofeither the disk or the I roll.

'13 represents a horizontally-movable slide or sole-carrier, which ismovable in guides at right angles with the shafts of the rolls 0 f, thecarrier being arranged at such height that a sole '8, resting onitsupper surface, will, by the movement of the carrier toward the left inFig. 3, be presented to the rolls, which will grasp the sole and removeit from the carrier,

carrier, as indicatedin dotted lines in Fig. 3, when it has passed themeeting points of the V rolls 0 and f, the gage 19 being permitted tothus drop by a depression 12 on the supporting-frame. The gage p is usedwhen the soles of right boots and shoes are being treated, the onteredge of the solebearing against the gage 10 as indicated in full linesin Fig. During the inward movement of the carrier by the operator thegage 19 remains in its operative position until the sole has beeninserted between the rolls and then drops to the position shown indotted lines just as the rolls commence to'grasp and move the soleforward, so that the gage does not oppose the forward movement of thesole by the rolls.

cated in dotted lines in Fig. 2, and is pushed onward by said gage untilthe sole is grasped and carried forward by the rolls, the gage pdropping to permit the sole to be moved off from the carrier by therolls.

q represents a heel gage, which is adjust- T ably mounted upon thecarrier and bears on the end of the heel of the sole 8. Said gage has agraduated plate g, which cooperates with a finger or pointer g on thesupportingframe in indicating the position of the gage q for soles ofdifierent sizes.

The operation of the machine is as follows: In treating a right sole theoperator places the sole upon the carrier, as indicated in full lines inFig. 2, and pushes the carrier inwardly until the sole-is grasped by therolls, the gage p at the same time dropping. The

rolls grasp the sole and move it onward, in-

denting the same, as shown in Fig. 5, the heel end of the sole tippingupwardly. The sole is delivered by the rolls at the back of the machine.When a left sole is being operated on, the operation is the same asabove described, excepting' that the outer edge of the 'sole is placedagainst the fixed gage 19 It will be seen that by the describedapparatus soles "can be quickly molded and-adapted foruse on spring-heelboots and shoes.

We do not limit ourselves to the use of the scoring-disk, as the rolls'0 and f, used without said disk, as indicated in Fig. 6, will mold orofiset the sole, though not as perfectly as when the disk is used. I

It is obvious that the machine may be adapted to other uses withoutdeparting from the spirit of the invention.

We do not limit ourselves to the particular details of construction hereshown, and the same may be modified in various particulars. Forinstance, instead of providing two gages for the sole-carrier, a singlegage may be used for both right and left soles, as in the modificationshown in Fig. 8, in which 1) repre sents a gage pivoted at p to thecarrier and adapted to occupy a position parallel with the shafts of therolls for left soles, as shown in dotted lines, and to be placeddiagonally or oblique for action on right soles, as shown in full lines,said gage being secured in either position by means of a clamping-nut pWe 'claim- 1. In a machine of the character specified, the combinationof a groovedbed-roll having a peripheral 'surface'at one side of thegroove, an indenting-roll arranged to enter the groove of the bed-roll,and a rotary scoring-disk located beside the indenting-roll in positionto cooperate with the peripheral surface of "the latter. g
